The Department of Energy is performing a resource assessment of the undeveloped conventional hydropower potential in the U.S. (Undeveloped pumped storage hydropower potential is not included.) The first graph titled "Modeled megawatts" shows the undeveloped hydropower potential for the 50 states, as estimated by the Hydropower Evaluation Software (HES). The second graph, titled "Hydroelectric net generation," shows what percentage of the power produced in the state comes from hydropower. The total modeled undeveloped capacity for the entire 50 states is approximately 30,000 MW. Go to the Hydropower Resource Assessment page for more information.
